Entity model inside inventory is animated every tick instead of every frame, making it look laggy

Entity model inside inventory is animated every tick instead of every frame, making it look laggy, which is especially noticable with low tick rate.

Steps to reproduce:

With an elytra:

• Equip an elytra
• Set tick rate to 5 (/tick rate 5)
• As soon as you start flying open inventory.
• Notice that entity's model animation inside inventory depends on tick rate.

With a camel:

• Set tick rate to 5 (/tick rate 5)
• Run the fiollowing command
  /summon camel ^ ^ ^2
• Open camel's inventory with shift+right click
• Notice that entity's model animation inside inventory depends on tick rate.
